Place Section Callout - Default drawing seed

Hello Pedro,

Thank you for raising your query. I would like to inform you that you need to choose any one of seed(for example: Arch Building Section) when you will place Section Callout for first time in the dgn file. There after you do not need to choose the same seed. Although if you would like to place other Section callout you can choose from dropdown menu. 

Thanks & regards,
Arindam
